2000 S Type stumbling Issue at 45 mph
#1
![Default](/forum/images/icons/icon1.gif)
Hi all, I purchased a 2000 S Type 4.0 , check engine light was on so I cleaned the intake plumbing and cleaned the Throttle body without removing it , I also cleaned the Air Assist Control Valve , I drove the car around for about 20 miles then punched the gas and the check engine light turned off. Now the car has a Stumbling idle after the engine has reached normal temperature , I notice this at a stop light . The car accelerates with no problem but when I reach 45 mph the engine stumbles /stutters , I give it more gas and the problem stops and runs great...
Has anyone had this issue or can someone guide me in the right direction to fix this problem..?

Welcome.
A quickie repost in the S Type section should have answers, but a code read would be my first best guess, then specifics can be sorted.
Also mention the kms/miles travelled, age of coils/plugs/O2 sensors/etc.
Might also help to know where you are, as some markets have stuff that other markets do not.

Welcome.
A quickie repost in the S Type area should get some answers.
I would slos add:
Your location, different markets, different stuff.
Kms/miles travelled.
Any codes stored.
Service schedule regarding plugs/coils/O2 sensors/etc.
Battery age, Not funny, many STRANGE issues have been traced to a dying battery.

Welcome to the forum Tmjag2000,
(I've merged your two identical Intro threads - please do NOT multiple post)
I can see you've already found your way to the S-Type forum so there's no need for a link to it from me. The 'HOW TO' thread at the top is a good place to start for information on regular issues.
Please remember to add vehicle details to your Signature to help others to give relevant advice. Go to the User CP button on the left of the top menu bar, then Settings & Options under Your Control Panel. Select Edit Signature and enter the details.
You can also visit the US Western Region forum by following this link https://www.jaguarforums.com/forum/western-us-ak-ca-nv-ut-hi-wa-id-38/ to find other members in your region.
Enjoy the forums.
Graham

Most likely coil pack(s), which may or may not set a DTC and turn on the MIL. Do you know if the spark plugs have been replaced?
If you encounter a situation when the MIL begins flashing, continuing to drive under those conditions causes permanent damage to the catalytic converters.
